ITunes 10.7 "upgrade" doesn't recognize my library
Just installed the latest iTunes (10.7). Instead of bringing up my library, it's showing me startup info about how to add music to a (presumably empty) new library.
The software was pointing to a newly created "ITunes Media" folder. I've used preferences to point to the actual location of my library (on an external drive), but I keep getting the same startup info screens, with no music (/movies/etc.) list (although the prefs now show the correct location for my media).
I know I can choose "Add to library" to get iTunes to construct a new list... but then I think everything will have the current date as "Date Added," which I don't want.
How can I fix this? Thanks for any help.
